ATTACHMENT FOR HEADLIGHTS FOR AUTOMOBILES.

Specification of Letters Patent.

Application filed June 23, 1915. Ser fl No. 353%.

To all wkom z't may concern.-

Beit known that I, EDWIN 0. WHEELER, a citizen of the United States,residing at Springfield, inthe county of Clark and State of Ohio, haveinvented certain new and useful Improvements in Attachments forHeadlights for Automobiles, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to an attachment for head lights for automobilesand the like and-more particulagly to a device for eliminating the glarewhich is usually present in a powerful head light.

The object of the invention is to provide a device which will eliminatethe glare-without dimming the light and without materially reducing theprojection of the light, so that the head light will still give amplelight and will project this light an ample distance for the operation ofthe machine.

To this end it is a further object of the invention to provide a shieldor deflector which will be of such a character and will be so arrangedas to deflect the light from the lamp against a selected portion of thereflecting surface of the head light.

It is also an object of the invention to provide a device of this kindwhich can be quickly and easily attached to the lamp of a head light andwhich can be produced and marketed at a low cost.

In the accompanying drawings, Figure l is a perspective view of mydeflector showing the same applied to an electric lamp bulb; Fig. 2 is arear elevation of the same: and Fig. 3 is a longitudinal sectional viewof a head light showing the bulb and deflector in elevation.

In these drawings I have illustrated one embodiment of my invention andhave shown the same as comprising a shield which is so arrang' d as toprevent the light from the lamp from reaching one longitudinal side ofthe reflecting surface of the head light, in the present arrangement,the lower surface, and from reaching any of the rear portion of thereflecting surface of the head light, thus allowing the light to reachonly the forward portion of a part of the reflecting surface. The lineof division between the front part of the reflecting surface,

' which is in the path of the light rays,

and the rear part of the reflecting surface, which the rays areprevented from reaching,

In the present embodiment of the invention I have shown the device inconnection w th an electric head light comprising the us'ual reflector,1, and electric lamp the latter consisting of a bulb 2 and a base 3adapted to be inserted in a socket at the rear end of the reflector andhaving pins adapted to enter slots and lock the lamp in the socket in a.well known manner. This is standard lamp construction and need not beshown and described in detail. As here shown the shield is formed ofmetal, preferably nickel plated, and constitutes a deflector for thelight rays, aswell as an opaque shield which prevents the rays fromreaching. certain parts of the reflector. This deflector com-- prises acup-shaped portion 5 adapted to receive one side of the bulb of anelectric; lamp and inasmuch as these bulbs are commonly spherical inshape this cup-like portion of the deflector is shown. as substantiallysemispherical, but it will be understood that its shape may be modifiedto adapt it to lamps of different kinds. This cup-like portion of theshield may be arranged to inclose any desired longitudinal portion ofthe bulb but ordinarily it is preferable that it should inclose thelower portion of the bulb so as to prevent the light striking the lowersurface, of the reflectorand I have so illustrated the same in thepresent drawings. j The reflector further comprises a l10od-like portion6 which coiiperates with the cuplike portion 5 to inclose the rear thebulb 2. This hood-like portion is shown a j as comprising substantiallythe fourth part Y of a sphere. Its lower edge overlaps the rear portionof the edge of the cup-shaped part 5 and its sides extend forward. to apoint near the greatest circumference of the bulb 2. The forward edge ofi'zhisghood- 'likc part of the deflector is, hojwevefr, out i portion of;I

lion

' tance in the rear of the greatest circumference of the bulb. The'pointat which the hood terminates may be varied to control the lightasdesired. The rear portions of the two parts of the deflector areconnected one to the other, by soldering or otherwise,

to support them normally in a fixed relation and are out away/to formanopening 8 through which the base 3 of the lamp projects, this openingbeing provided with lateral extensions 9 to permit the passage of thepins & of the base.

By connecting the two parts of the defiector at their rear portionsonlyl enable the two parts to be adjusted relatively one to the other tofacilitate the insertion of the lamp. It will be understood, however,that the two parts of the deflector may be formed andconnected in anydesired manner, the separate formation being here adopted formanufacturing reasons only. \Vhen the base of the lamp has been insertedin the opening 8 of the deflector the deflector will be supported by thelamp itself. To maintain it in its proper relation thereto I prefer toprovide the deflector at the forward end of the lamp with a lip 10having an opening 11 to receive the tip of the bulb. Preferably, awasher 12 is interposed between the bulb and the lipto form a snugconnection. The opening 11 ishere shown a as a. transversely extendingslot to permit of a slight play or relative displacement of the partswithout injury to the lamp.

Vi ith a shield of this character attached to the lamp of a head lightand arranged in. the position shown it will .be apparent that the lightis prevented from reaching any part of the lower portion of the reflector and from reaching any part of the rear portion of the reflector,thus causing the rays to be directed toward the upper forward portion ofthe reflector, which portion of thereflector will project the rays along distance in advance of the head light but will so condense the raysas to eliminate theglare.

It will be further apparent that the device is a very simple one tomanufacture and that it can be produced and sold at a low cost and canbe readily attached to ahead light; andthat the bulb can be readilyremoved when burned out and a new one sub- .stituted therefor.

Having thus fully described my invem tion, what I claim as new anddesire to secure by Letters Patent, is i 1.,A light deflector for thebulb of an electric head light comprising an opaque reflecting shieldhaving a part to inclose the lower half of said bulb. having anotherpart to lnclose substantially the upper rear quarter of said bulb, thetwo parts of said shield being capable of relative movement to permitthe bulb to be inserted in the shield.

A light deflector for the bulb of an electric head light comprising ashield having a substantially semi-spherical lower part to receive thelower half of the bulb and having a hood-like part to incloscsubstantially the upper rear quarter of said bulb, said parts of saidshield having their adjacent edges overlapping and having theirrearpor-tions cut away to form an opening to receive the base of thebulb.

3. A light deflector for the bulb of an electric head light comprising asemi-spherical shield of opaque material and having reflecting qualitiesadapted to inclose substantially one-half the lower portion of the bulb,an upper hood overlapping said semispherical shield and adapted to coverthe said hood-like'part overlapping and adjustable relatively to eachother to-allow the insertion of said lamp.

In testimony whereof, I atlix my signature in presence of two witnesses.
